Here, the user can add the tasks item they did for each day, so they can bill the client for each week. This page performs calculations, generates an invoice and lets the user store and retrieve the invoice for this week.

When the user interacts with invoices:

• The page changes in state

• Adds and changes menu option

• Allows users to recover items stored in the database
